The Pegasus range offers extreme high temperature
calibration in an easy to use portable package - ideal for
the calibration of high temperature thermocouples. It has
been designed for fast heating and finds applications in the
glass, electrical power, automotive and material processing
industries.
A Blackbody target can be added for the calibration of
infrared thermometers.
The standard insert has four 8mm pockets 80mm deep.
The metal insert is strategically placed beneath 50mm of
insulation to provide optimal performance over the radiant
temperature range.

The optional Blackbody target is used with a specially
angled Type R thermocouple that sits immediately behind
the target area.
These award winning calibrators are easy to use and are
available in three versions – the Basic, the Site and the
ADVANCED. The Basic has a digital display of set and
nominal temperature, the Site additionally includes an inbuilt independent temperature indicator for a reference
probe. The ADVANCED controller has inputs for reference
and test thermometers with a further range of sophisticated
features including automatic temperature cycling, secure
data logging and full colour high resolution display.
The B model should be used with an external reference
probe and indicator, such as the milliK. The thermocouples
UKAS Calibration available for these systems - International Traceability - Best Practice
under test should be calibrated by comparison to the
external probe.
All models include I-Cal Easy LOG software and the
ADVANCED models additionally include software to
manage logged data and configure the unit, see page 14
for more details.
